Home Exemplifies High Performance Building With Faswall

by

Jack Clark high performance home ColoradoOur last blog post discussed the theory behind designing and building high performance homes. For this post, we’d like to discuss the practice of building high performance homes with Faswall ICF wall forms.

Jack and Carolyn Clark’s 3,200 square foot home in Ft. Collins, Colorado exemplifies many components of high performance building. The home is very energy efficient, thanks in part to Faswall’s extremely high thermal mass. It’s built to last for at least 300 years, so it’s quite durable. High-quality materials such as 3-0 windows and a propane/heat pump HVAC system ensure excellent life-cycle performance. Since both Jack and Carolyn have allergies, they used building materials designed to ensure good indoor air quality and occupant productivity.

The Clark residence sits on an acre of land Jack’s parents bought in 1972. Their 750-square-foot house overlooked Horsetooth Reservoir and was intended to be a summer home. But his parents made it their permanent residence until they passed away.

Jack wanted to stay on the property, but he had a different vision for his forever home. He wanted more space and a house that could be passed down to future generations of his family. Jack had his parents’ old home deconstructed in 2012, then started looking into suitable building materials for a new structure.Jack Clark high performance home Colorado

“Carolyn and I wanted to incorporate as many progressive products and techniques as possible for the build,” Jack says. “I was looking for a unique, thermally-efficient, cost-effective approach. We met [ShelterWorks co-owner] Paul Wood at a home and garden show in Denver and became very interested in his building method right away because the Faswall system allowed for well-insulated, high internal thermal mass wall construction.” Local Faswall representative Mark Maricle was also a great resource throughout the building process.

Faswall was also a good fit with some of Jack and Carolyn’s architectural requirements. They both grew up in a section of New Jersey with many Dutch Colonial style homes. They liked the deep window wells found on those structures, which is an added bonus of using Faswall’s one foot by two foot blocks. They wanted to finish the interior walls with smooth plaster and the exterior with lap siding, which meant using a building material flexible enough to accept any type of finish.

Once he selected Faswall, Jack went in search of a builder. He wanted someone willing to work with a non-traditional material. He also needed someone with enough attention to detail to build a high-quality home capable of lasting for 300 years.

Jack Clark high performance home ColoradoHe found both in Matt Doner of Traditional Roots Joinery & Construction in Ft. Collins. Matt is primarily a timber frame builder, but he was excited to combine his carpentry skills with the easy-to-use Faswall blocks.

The home that evolved incorporated the best of both. Jack says one of his favorite features in his Faswall home is the beams crossing the vaulted ceilings. They’re made with Northwest fir and locally-sourced Ft. Collins walnut. Jack also likes the elevator, which makes moving people and furniture around the space much easier; the highly efficient windows and sliding glass doors, all of which were manufactured by a Colorado company; and those deep window wells. The home has the exact same orientation as his parent’s house, which gives the family views of the reservoir.

Function dictated design for the house, Jack says, and the layout is a great fit with the family’s needs. An open floor plan upstairs makes entertaining more enjoyable. A mud room/laundry room/bathroom accommodates muddy dogs and gardeners, as well as sopping boots on snowy days. The Clarks hope to eventually add a wrap-around porch, much like the ones on the Dutch Colonial homes they remember so fondly.

Jack has tracked the home’s performance since he moved in and is very pleased with what he’s found. Their electricity comes from the rural cooperative, and the home has a propane/heat pump furnace for heating and cooling. “The rural electric bill averages $100 per month, and we use no more than 21 gallons of propane per month,” he says. “Our utilities (other than water) average $125 per month for a 3,200 square foot home with three adults living here full time.”

Thanks to the insulative value of the Faswall blocks, as well as strategically placed insulation, the home stays comfortable no matter how warm or cool it gets outside. “The thermal mass maintains the inside temperature better than convention builds,” he says. “Therefore the HVAC does not have to ‘catch up’ as much to maintain temperature. When we have 50 degree days and 20 degree nights, the house will lose no more than one to two degrees overnight.”Jack Clark high performance home Colorado

Jack has several pieces of advice for anyone building with Faswall. It’s important to look at the whole home when planning for energy efficiency. “Besides picking very efficient heating/cooling equipment, insulate the ground floor slab from the ground below it and the footers,” he says. “Consider using varied insulation types according to where the insulation is installed and the clearances required.

“Do not be stingy with glazing,” Jack continues. “Look closely at what the window and door frames are made of. Fiberglass is non-conductive and will not warp.  Consider how much sun and what type of sun should pass through the glazing. All heat and light can be controlled to the owner’s benefit. Choose a window and door supplier that understands this and can customize products to control the heat loss and gain.”

Jack Clark high performance home ColoradoAlthough Jack didn’t build his own home, he has this advice for do it yourself home builders: “It pays to get tricks from Paul or one of his representatives. It will make the job go smoothly.”

High Performance Homes Will Define The Future of Building

by

High performance, green builidng, ICF wall form, FaswallFor years homeowners, contractors, architects and material manufacturers have focused on “green building,” or constructing homes and businesses that have less of an impact on the planet. But more and more, they’re moving away from the term green building in favor of “high performance building.” Industry experts believe this phrase does a better job of explaining the myriad goals they hope to meet, including lowering a home’s carbon footprint, saving the owner money on energy bills, and creating a structure that will last for a long time.

Since the term high performance building is so new, there’s still a lot of confusion about it. What does high performance building mean? Why is high performance building better than green building? How do you build a high performance home, office, warehouse or other structure? We’ll explore these questions in more depth.

The National Institute of Building Science defines high performance building as creating structures that “integrate and optimize all major high-performance building attributes, including energy efficiency, durability, life-cycle performance and occupant productivity.”

That’s a bit of a mouthful. Let’s break it down.

Energy efficiency is one of the most important parts of high performance building. Decreasing your home’s energy usage is important for many reasons. In the United States, electricity production is the largest contributor to climate change, creating 31% of our total greenhouse gas emissions. Forty-one percent of all the energy Americans produce is consumed by residential and commercial buildings. If people can significantly lower the amount of energy needed to power their homes, they can make a big difference in the fight against climate change.

high performance, green building, ICF wall form, FaswallIncreasing your home’s energy efficiency can help you save money on your utility bills, and get you closer to the goal of living partially or completely off the grid. For people interested in homes that utilize net zero, Passive House or passive solar principles, building an energy efficient structure is a must.

Durability is another important component to a high performance home. When you construct a building that will  last for a long time, all the energy and materials that went into making it remain there. From an environmental perspective, saving the embodied energy of the home is vital because it keeps materials out of landfills and decreases the amount of new materials that have to be harvested, mined and processed. The longer a home stands, the longer you can retain that embodied energy.

The average high performance home is designed to last for up to 200 years. Because it’s built to such high standards and with such quality materials, it’s better able to withstand natural and man-made hazards such as severe weather (hurricanes, tornadoes, tsunamis, etc.) and wildfires. If you’ve ever dreamed of having a house you can pass down to your children and grandchildren, building a high performance home will help you fulfill that dream.

high performance, green builidng, ICF wall form, FaswallLife-cycle performance is similar to durability. It takes into account how well the building performs over its long life.

Having good life-cycle performance means the home meets all the owner’s goals (no or low utility bills, lower maintenance costs, good indoor air quality, etc.). It does that now and into the future. A high performance building should be built well enough and smart enough that it doesn’t require a lot of time or money to maintain. Not only is it made with high quality materials, it utilizes the best in building science to reduce mold, rot and other problems. Some examples of smart building science include looking at a building’s envelope, thermal mass, materials, heating and ventilation systems, and defense against rain and the natural elements.

We believe occupant productivity comes down to the health and comfort of the people who live and work in the building. One of the biggest considerations for a healthy home is good indoor air quality. In older homes, air and moisture have many places to enter the house, but few places to escape. As a result, the air is full of dust mites, mold, bacteria, pollen and other allergens. It’s estimated that the air quality inside a typical home is two to five times worse than the air quality outside. That’s concerning because Americans spend 90% of their time indoors.

In high performance homes, the interior air is continually exchanged with outside air that has been filtered and tempered. That means mold is less likely to form inside the walls, allergens and pollutants don’t enter the home, and you and your family have a healthy, pleasant living environment. High performance homes are also built with non-toxic materials that will not off-gas formaldehyde, phthalates, VOCs, flame retardants and other harmful substances into the house.

high performance, green builidng, ICF wall form, FaswallAnother way high performance homes increase occupant productivity is by providing a high level of comfort. All the building science involved in creating high performance homes means structures have a consistent interior temperature, no drafts and very little noise. They are clean, full of light and smell good.

In addition to the four attributes described above, we would like to add that high performance homes are built with what we’ve come to know as green building materials. Green building materials contain recycled materials, are easy to recycle at the end of their lifecycle, have a minimal negative impact on the planet when they’re harvested and manufactured, and/or don’t contribute to bad indoor air quality.

High performance buildings should also be aesthetically pleasing and functional for the homeowner. If a building meets all its goals in terms of energy efficiency and occupant productivity, but it’s ugly or has a bad floor plan, no one will want to live there. It increases the likelihood that the building will be torn down at some point.

If you’re looking for the perfect building material for your high performance home or office, Faswall is an excellent choice. Faswall ICF wall forms create structures that are extremely energy efficient thanks to their high thermal mass.

high performance, green builidng, ICF wall form, FaswallFaswall is made with a blend of recycled wood and concrete, which makes the blocks extremely durable. Homes can last for well over 200 years. The mineralized wood composition ensures Faswall resists pests and will not mold or rot. Wood and concrete are completely organic materials that will not off-gas into the house.

The interior and exterior of a Faswall home, office, church, outbuilding or other structure can be finished any way you want. As you can see from the photographs, the structures look beautiful when they’re done. Faswall blocks are easy to work with, whether you’re an experienced contractor or a DIY home builder.

How Faswall Resists Fire and Wet Conditions

by

Faswall is able to resist even extreme heatFaswall green building blocks are made with a special blend of wood and concrete. These 100% organic (and 60% recycled) materials make it an ideal building product for many reasons. Faswall creates homes, offices, warehouses and other buildings that are extremely energy efficient. Faswall green building blocks are a great place to begin if you want a home with superior indoor air quality. Their ability to resist mold and mildew make them ideal for wine storage, beer breweries and many other uses.

But there’s another reason building with Faswall green building blocks is a great idea. They make homes that are extremely durable. The blocks are very strong and create structures that can easily stand for hundreds of years. Termites, carpenter ants and other pests have a hard time eating into them because the cement outer layer completely impregnated the blocks with a mineralized coating.

Faswall is fire resistant

In the western United States and Canada, where much of the region is in a historic drought, we are very concerned about forest fires. John and Patti O’Connell, who were interested in building a Faswall home, were also concerned about the fire resistance of the blocks. So John did his own unscientific test, which you can see in this video.

Basically, John took a propane torch and held the flame directly against a Faswall block for two minutes. The direct heat burned a tiny hole in the block, and made the insulating insert in the block smoke a little bit, but it didn’t catch on fire. In fact, at the end of the test, John was able to lay his hand on top of the block because it had barely gotten warm.

“I don’t think you have to worry about forest fires,” he says. Especially since, as he says a moment later, “This is obviously a hell of a lot more heat than any forest fire is going to deliver.”

Faswall holds up great in wet climates

We hope some day it will begin to rain in the western states again. When it does, we expect we’ll see a lot of it. Those of you who live in southern states and occasionally fall victim to hurricanes, flooding and major storms may see even more.

Faswall green building blocks are also able to stand up to very wet conditions. Tom Bristol of Purple Flattop Architecture in Chewelah, Washington was dubious about just how much the wood/concrete IFC wall forms would be able to resist water. He decided to run a test of his own.

Tom took a Faswall block and dropped it in a bucket of water. And left it there for 10 years.

The result? The Faswall green building block has seen little to no deterioration over that time.

Now, we’re certainly not recommending you build your home by a flood plain, a beach frequently ravaged by hurricanes or tsunamis, or an area prone to forest fires. But should disaster strike – which is more likely as climate change continues and the world’s weather gets more unpredictable – Faswall green building blocks will give you more reassurance that your home will last and stay safe.

Tibetan Buddhist Monastery Chooses Faswall

by

We’re honored that the nuns at Sravasti Abbey, a Tibetan Buddhist monastery in Newport, Washington, chose to construct their newest building with Faswall green building blocks. Chenrezig Hall provides a dining hall, commercial kitchen, administrative offices, and temporary residences for visiting nuns and monks. (Watch the video below to learn more about the project.)

Project contractors Alpha & Omega Construction from Oldtown, Idaho recommended Faswall green building blocks because they offers several beneficial characteristics that were important to Sravasti Abbey’s residents. Faswall blocks create incredibly strong, durable structures that will last for generations. They are made with a blend of wood and concrete, which means they resist damage from pests – a plus since the abbey is surrounded by forestland.

Abbey entry Chenrezig HallFaswall is a made from 60 percent recycled materials, which is only one of the things that makes it an outstanding green building material. The blocks have unrivaled thermal mass, which means they create warm, comfortable buildings. No cold air seeping through cracks in this building! Structures built with Faswall green building blocks are also extremely energy efficient, which helps keep utility bills low.

The word “Chenrezig” means “The Buddha of Compassion,” and we have no doubt that all who enter this sacred center will feel compassion and love from its residents.

Chenrezig Hall is a great example of how Faswall green building blocks can be used for commercial buildings. Can we help you build an office, medical or dental center, shopping plaza, industrial building, or your own place of compassion? Please contact us today for more information.

 

Do It Yourself Home Builder Shares Benefits of Thermal Mass

Do it yourself home builder shares benefits of thermal mass As you read about the advantages of building a home with Faswall green building blocks, you’ll notice we give a lot of attention to the product’s superior thermal mass. What is thermal mass? And why is thermal mass an important thing to consider when building an energy efficient, environmentally friendly home?

Your Home, a green home building website developed by the Australian government, defines thermal mass as “the ability of a material to absorb and store heat energy.” If a material takes a lot of energy to heat up and cool off (like bricks and other types of masonry), it is said to have high thermal mass. On the other hand, if a material does not require much energy to go from hot to cold (like wood), it has low thermal mass.

If done correctly, thermal mass is an important principle in green building because it can help you increase your home’s energy efficiency and lower your energy bills. Products with high thermal mass absorb and release heat slowly, which is actually to your advantage. On cold days, you have a steady supply of warmth radiating into your home over a long period of time. On hot days, the building heats up really slowly and gradually dissipates that heat once it begins to cool off outdoors.

Faswall green building blocks are made with a mineralized wood product, which gives it a high thermal mass. Each block comes with an insulating insert, and once stacked, builders pour a pea gravel concrete aggregate mix down two cores in the center of each block. This makes the building’s thermal mass even higher. The end result is a home, office, or commercial center that will keep you cozy warm in the winter and nice and cool in the summer. The fact that Faswall green building blocks are made with 60 percent recycled materials is an added benefit for people interested in green, environmentally friendly homes.

Ben Turner, a retired nurse practitioner and do it yourself home builder, can attest to the benefits of high thermal mass. He used Faswall green building blocks to construct a one-story home with a daylight basement in southwest Washington. “This house weighs about 600,000 pounds,” Ben says. “When it gets warm it stays warm. In the summertime, if it gets hot it stays cool on the inside. It’s an amazing place to live.”

“I just don’t have to worry about heating,” he adds. “If I don’t want to build a fire on a day like this, where it’s 40 degrees out, it still won’t get cold inside. It holds the heat that much because again, the house is so heavy. There’s so much thermal mass in there.” (Ben shares more of his story in the video below.)

In addition to using the Faswall green building blocks, Ben put in lots of south-facing windows to allow in light and solar gain. He uses a masonry stove in the center of the house to provide radiant heat in the living space and pre-heat water for the hydronic floors in the basement. The combination of this heating system, the home’s passive solar design, and Faswall’s great thermal mass means he is spending around $100 a month on his electric bill.

Ben notes that he was first attracted to Faswall green building blocks not because they create extremely energy efficient homes, but because they are exceptionally durability. Ben remodeled and worked on all the other homes he’d lived it. When it came time to build the home he would enjoy in retirement, Ben says, “I just wanted to … build it and it would be done and I wouldn’t have to maintain it. So that’s what we did here.”

Since Faswall is made with a combination of recycled wood and cement, it does an exceptional job of standing up to the elements, pests, and other things that can damage a home. Ben used lime plaster, also called loam plaster, for the outside of the structure. The product is made with a combination of sand and limestone, Ben notes, and “it’s been used for thousands of years. The wonderful thing about it is it lasts forever. It just gets harder over the centuries. Like a limestone cave, if it cracks or water runs in it, it just heals up the cracks, so it’s a very low-maintenance exterior.”

Another feature that makes the home so easy to care for is that it doesn’t require painting. To achieve the attractive reddish-brown color on the outside, Ben sprayed the lime plaster with ferrous sulfate, the main ingredient in many brands of moss killer. “It was a very fun process and very easy to do,” he says. Best of all, it cost about $5 to coat the entire exterior.
